Enamel removal technology for enameled wire: Here, we will discuss various issues related to the enamel removal technology of enameled wire. Of course, first of all, it is necessary to understand the different types of enameled wire. Based on the material of the enameled wire, we classify them into three categories: copper enameled wire, aluminum enameled wire, and aluminum-clad copper wire. Classified by temperature resistance level (i.e., heat resistance grade): Y (90°C), A (105°C), E (120°C), B (130°C), F (155°C), H (180°C), H+ (200°C), C (220°C). Based on type of coating, function, shape, and weldability, they are further divided into: acetal-coated wire, polyester-coated wire, epoxy-coated wire, polyimide-coated wire, polyamide-imide-coated wire, polyurethane-coated wire, self-adhesive wire, polyester-imide-coated wire, composite enameled wire, nylon wire, corona-resistant wire, magnetic wire, self-lubricating wire, flat enameled wire, stranded enameled wire, aluminum-clad copper wire, etc. There are a vast variety, leaving one in awe. Under these circumstances, it has also increased the difficulty for us in developing technologies for removing the paint from enameled wire. From direct welding to manual scraping, from paint strippers to paint removers, there are various methods, but the main purpose is: removing paint – then soldering. We will not discuss wires that can be welded directly at low temperatures here; our focus is on wires of grades 130, 155, 180, 200, and 220 that cannot be welded directly. With the advancement of chemical technology and the implementation of the ROHS standards, to improve efficiency, the most suitable agent for stripping paint in factories is: enameled wire paint stripper (also known as stripping solution, paint removal liquid, peeling agent, or paint remover). Therefore, enameled wire stripping agents must meet the following requirements: 1. Comply with ROHS limit standards, as determined by testing institutions such as SGS. 2. The copper and aluminum wires obtained after stripping the paint must be shiny, free from oxidation, and easy to weld. (There is currently a type of paint-removing powder available on the market for removing high-temperature coatings; only Dongguan Bont BT enameled wire paint-removing powder can make aluminum wires as shiny as a mirror. Powders from other manufacturers cause severe corrosion of the aluminum wires – after painting removal, the wires become corroded, dull, pitted, and rough, which severely affects welding or leads to the natural separation of the solder layer from the aluminum wire after welding, resulting in circuit breaks. ) 3. Fast paint removal speed with minimal harm to the human body.
